Width=3
Lenght=17.2
Height=5.5
What is the lateral surface area of the rectangular prism?
A.283.8
B.292.4
C.325.4
D.407
@Ms. Sue but I got 325.4 which is the surface area
S.A = 2(W * L) + 2(W * H) + 2( H * L)
@Ms. Sue but how do I get the lateral surface area?
You'll get the lateral surface area with that equation.
In this website a rectangular prism is also called a cuboid.

Yes, that's right!
To find the lateral surface area of a rectangular prism, we need to calculate the area of the four side faces excluding the top and bottom faces.
Formula for lateral surface area of a rectangular prism:
Lateral surface area = 2 * (Length * Height + Width * Height)
Given values:
Width = 3
Length = 17.2
Height = 5.5
Substituting the given values into the formula, we get:
Lateral surface area = 2 * (17.2 * 5.5 + 3 * 5.5)
Calculating the expression inside the brackets, we get:
Lateral surface area = 2 * (94.6 + 16.5)
Adding the values inside the brackets, we get:
Lateral surface area = 2 * (111.1)
Multiplying 2 by 111.1, we get:
Lateral surface area = 222.2
Therefore, the lateral surface area of the rectangular prism is 222.2.
